Tell install I have 32MB video ram
I'm sure this is one of those miscellaneous parameters you can put in at t he beginning of the install. I have one of those shared RAM arangements, and the installer decides I have only 16MB. Then it croaks on 1240x1048, too, which is my display's native resolution.
While we're at it, how do I know what idebus=?? should be? I suspect 33 is low for a new box. (Does it matter?)
